CHALLENGE ACCEPTED! THE 2024 KTM EXC RANGE IS HERE TO REDEFINE LIMITS
Sporting 95% new components, the 2024 KTM EXC range is moving the goalposts further than ever before. Featuring an all-new frame, revolutionary closed-cartridge suspension, refined bodywork, LED headlight, and industry-defining technology, the latest generation of KTM Enduro machines are ready to accept any challenge.
With over three decades of racing experience and more than 126 World Enduro titles in the trophy cabinet, KTM has remained the weapon of choice when it comes to taking on the world’s toughest races. For the 2024 model year, the KTM EXC nameplate continues to raise the bar in the areas of performance, development, and innovation with its most radical transformation to date.
An all-new hydro-formed, laser-cut, and robot-welded frame forms the backbone of the 2024 KTM Enduro range. This brings new longitudinal and torsional flex parameters for unmatched rider feedback, energy absorption, and straight-line stability to the riding experience but also provides the foundation on which the 2024 model range is built.
Upfront, the KTM EXC and EXC-F range now boast an all-new 48 mm WP XACT Closed Cartridge spring fork, featuring a new mid-valve piston concept that optimizes oil flow within the cartridge.
The KTM Enduro models continue to feature the proven PDS shock system, which for 2024 is updated and optimized to work fluidly with the new frame concept. This is mated to a new WP XPLOR PDS rear shock.
As an industry first, the suspension at both ends remains fully adjustable for compression and damping by way of hand clickers, without the need for any tools, and easy set preload adjustability on the rear.
An all-new lightweight 2-piece subframe, constructed from a combination of polyamide and reinforced aluminum. It delivers outstanding handling and rider feedback, as well as remarkable robustness. All electronic components, including an all-new Offroad Control Unit, are fully integrated into the subframe for easy access and improved protection.
More notably, the 2024 KTM EXC range benefits from new bodywork all around. This has been developed with input from the Red Bull KTM Factory Riders to deliver an improved rider triangle for better knee contact, especially standing on the pegs.
A new front fender design now also features mud-repelling fins for expelling dirt and mud from hitting the rider or radiators, while a new 8.3 liter – 4-stroke – and 8.9 liter – 2-stroke – transparent, polythene (XPE) fuel tanks for easy fuel level monitoring complete the bodywork package.
Monitoring the electronics comes courtesy of a totally independent OCU under the seat, which replaces the use of electronic fuses and relays. In the event of any electrical component failure, the outputs are deactivated individually, with the error status of each unit indicated by a red or green LED light. This makes for quick and easy troubleshooting on the trail.
In terms of engines, the 2-stroke model range once again takes its place as the leader of the oil-burner paddock, debuting new electronic Throttle Body Injection technology. Dubbed TBI for short, it provides almost carburetor levels of ultra-smooth power delivery, while eliminating the need for re-jetting at different altitudes.
The reed valve case has also received an important design update, with new plastic flaps on the outside of the reed valve case for improved sealing of the intake tract. This new design avoids fuel excess in extreme up- or downhill sections which could lead to the fueling running rich.
A beneficial side effect of the new electronic fuel injection and the ECU is implementing the new electronic exhaust control, allowing for two different engine maps, selectable via an optional Map Select switch.
The 2024 KTM EXC 2-stroke range will once again consist of the following model line-up:
● KTM 150 EXC
● KTM 250 EXC
● KTM 300 EXC
The 4-stroke model range provides the most concise offering of models. All models in the 4-stroke range benefit from class-winning engines, engineered to deliver massive torque down low with an explosive power delivery at higher RPMs.
An improved center of gravity was achieved by tilting the engine 2° backward and repositioning the front sprocket 3 mm lower, for greatly improved handling and maneuverability. Together with the benefits of mass centralization and reduced weight, the anti-squat behavior of the chassis was significantly improved making for improved traction on extreme inclines and powering out of corners in special enduro stages.
The 2024 KTM EXC-F also debuts the optional addition of Traction Control and for the first time ever on an enduro machine – a Quickshifter function. The latter makes for clutchless upshifts from 2nd to 6th gear, allowing riders to keep the throttle pinned open while changing through the gears for improved control. These can be toggled on or off via an optional and newly designed Map Select Switch.
The 2024 KTM EXC-F 4-stroke range consists of the following models:
● KTM 250 EXC-F
● KTM 350 EXC-F
● KTM 450 EXC-F
● KTM 500 EXC-F
The 2024 KTM EXC range is the culmination of many years at the top end of Enduro competition, bringing together a dynamic combination of race-bred performance, ergonomics, and technology to challenge any terrain and redefine the limit.
As always, and thanks to KTM’s global networks of dealers, the availability of support and parts needed to compete at the highest level is easily accessible, with the added availability of dedicated KTM PowerWear and KTM PowerParts which have been designed to allow for the highest levels of performance, protection, and mobility for all offroad riders and racers.

Getting READY TO RACE has never been easier. Thanks in part to its all-new suspension, the 2024 KTM EXC range boasts a totally tool-free suspension setup at both ends. At the rear, our legendary, race-winning PDS technology features an all-new shock absorber design with hand-adjustable dual compression controls. This allows riders to adjust high- and low-speed settings in a matter of seconds. On the front, the forks are also easily adjusted thanks to hand-adjustable clickers on the bottom of the fork shoe and on the fork top cap, making changing settings on the fly as easy as twisting the throttle.
DEEP BREATH
Air filter box
Maximum airflow with minimal water intrusion, a new air filter box is designed with precisely positioned inlet ducts aimed at preventing air deformation and maintaining filter protection. An enduro-specific splash protector under the airbox prevents water or dirt from splashing up from the rear wheel, while the Twin Air filter and air filter support design feature a simple fail-proof mounting system for safe and accurate filter installation, ensuring the air filter is easily accessed, without tools, for fast track-side maintenance.
FULLY FUELED
Fuel Tank
The transparent, polythene (XPE) fuel tank is a signature element of the KTM Enduro lineup. Not only does this let you keep an eye on your fuel level with a quick glance, but years of development mean it’s the strongest, most reliable fuel tank yet. For 2024, a one-piece fuel pump and filter improve the fuel supply allowing the tank to be emptied further at a low fuel level. And with 9 liters of fuel at your disposal, you can hit the trail or track with utmost confidence.
SWITCH IT UP
Switchgear
For 2024, the entire KTM Enduro range receives new, easy-to-use switchgear. On the right side of the handlebar, you’ll find a new start/stop switch, and on the left, an new and optional Map Select switch will allow riders to choose between Map 1 or Map 2.
TORQUE ABOUT IT
Engine
Let’s start with the numbers; 49 hp, 43,8 Nm and 24.6 kg. This new 300cc 2-stroke powerplant not only brings a new choice into the E3 Enduro category, but remains the idea choice for Enduro riders wanting maximum power and torque at the least possible weight. Another reason why the KTM 300 EXC engine sets the benchmark in the competitive Enduro E3 class and in hard enduro races all over the world.
FUELING SPEED
Throttle Body Injection
Forget TPI, the 2024 KTM 2-stroke Enduro models feature all-new electronically-controlled Throttle Body Injection – or TBI. The ECU, together with a new Keihin 39mm throttle body,calculates the ideal air-fuel mixture by constantly analyzing water temperature, air temperature, ambient pressure, and pressure within the crankcase, the rpm, and the throttle position to ensure the smoothest and most consistent power delivery in the most gnarly of enduro conditions.
Powervalve
For 2024, the reed valve case has received an important design update along with electronic exhaust control. New plastic flaps on the outer reed valve case provide improved sealing of the whole intake tract, preventing excess fueling in extreme up or downhill sections which could lead to rich engine settings.
SMARTER ELECTRONICS
Offroad Control Unit
An all-new Offroad Control Unit – or OCU – under the seat replaces all the electronic fuses and relays. All outputs are switched depending on signals from the voltage regulator and the ECU continuously. In the event of over-current, outputs are deactivated individually. This makes for easy error detection as the status of each output is indicated by a red or green LED light. This means diagnosing an electrical issue out on the trail is as easy as lifting the seat, and there’s no more need to carry fiddly fuses.
PICK YOUR POWER
Selectable Engine Maps
Designed for easy operation, a newly developed map select switch is available as an optional extra on all KTM EXC models and allows for the easy selection of 2 unique engine maps. Map 1 is the standard, more linear, and predictable power map, while map 2 is a more aggressive map for added throttle response and more crisp, explosive power output.
LITHIUM POWERED
Battery & Wiring Harness
As with the rest of the 2024 2-stroke EXC range, the KTM 300 EXC is fitted with a proven, reliable electric start system.

Binging the Braaap! Thanks in part to the KTM 300 EXC’s new, more compact engine design, the header pipe is designed with the target of achieving more ground clearance and reducing the risk of damage when riding over deep roots, ruts, or climbing steep rocks. The silencer is crafted from lightweight aluminum and is stylishly finished off in a black coating that highlights its premium quality.
BUILT TO BE THE BACKBONE
Frame
Specifically engineered for longitudinal rigidity, the 2024 2-stroke KTM EXC range is engineered around an all-new black powder-coated frame providing exceptional rider feedback, energy absorption, and high-speed stability. This has been achieved by repositioning the rotating masses in the frame and the inclusion of a forged steering head connection. New parallel frame mounts also improve flex characteristics, while the footrest mounts have also moved inwards, slimming things down. And when the ride comes to an end, a completely redesigned forged one-piece side stand ensured things your enduro weapon stands proud.
MORE THAN A SUBFRAME
Subframe
A new ultra-light lightweight subframe takes charge at the rear of the main frame, featuring a 2-part polyamide and reinforced aluminum construction. With the help of computational dynamics, a specific rigidity was engineered into the subframe, to deliver outstanding handling and rider feedback. The new subframe is also shorter, more compact, and more robust than the previous generation, with the ability to bend and flex in the event of a crash, rather than break. The subframe fully integrates the electronic components, without any extra need for brackets, holders, or unnecessary fixtures.
UNFLAPPABLE FRONT END
WP XACT Closed-cartidge Fork
An all-new 48 mm WP XACT Closed Cartridge spring fork finds its way into the KTM Enduro line-up for 2024. Providing fast and consistent damping, optimized oil flow, and a new hydro stop in the last 68 mm of the stroke, the forks ensure unmatched performance at any level. New fork protection rings also provide improved protection against dirt intrusion. Best of all, the new fork allows for full adjustment of compression and rebound without the need for any tools.
GET THE POWER DOWN
WP XACT Shock
Remaining a hallmark of KTM Enduro weaponry, an updated PDS rear shock concept sees a new shock mount that significantly improves the anti-squat behaviors of the chassis. This remains the most reliable and maintenance-friendly option for competitive enduro racing. Moreover, an all-new WP XPLOR PDS rear shock now takes charge at the rear, weighing 380 g less than the previous generation unit. It features a new compact design, new bearings seals, and a new main piston for optimized oil flow, and improved, consistent damping, as well as providing full adjustability thanks to easy-to-use hand clickers for adjustments on the fly.
WHERE RUBBER MEETS DIRT
Wheels and Tires
The KTM 300 EXC rolls on a set of high-strength GIANT alloy wheels coupled to CNC-machined hubs and aluminum nipples. These are wrapped in a set of ultra-grippy Maxxis MaxxEnduro tires providing exceptional traction in all conditions.
HOLD THE LINE
Stability
The 2024 KTM EXC range remains rock-solid at any speed thanks to a repositioned and forged steering head connection and CNC-milled triple clamps. Made from high-grade aluminum, these feature optimally tuned steering stem stiffness, perfect alignment of the fork tubes, and precise geometry of the fork clamps to ensure highly responsive and smooth fork action – not to mention unwavering stability for those ultra-fast flat-out special stages. Newly designed, topology-optimized rubber-mounted bar mounts provide an increased grip surface for less handlebar twist They come with a fixed mounting, providing the perfect amount of flex for the forged triple clamp setup.
FIGHTING FATIGUE
Energy Absorbtion
Besides the expertly crafted, hydro-formed, laser-cut, and robot-welded frame being engineered to provide exceptional rider feedback and straight-line stability, a number of components mean the frame acts as a “shock absorber” making for a less harsh ride, resulting in less rider fatigue over many hard laps. A new shock mounting, no longer connected to the main tube, significantly improves the anti-squat of the chassis. In contrast, a new, service-friendly one-piece steering head seal provides improved reliability. The closed-head tube design also provides a new routing for the fuel overflow. And lastly, a new forged one-piece side stand means no more sinking feelings when parking up.
SEE INTO THE FUTURE
LED headlight
Lighting the way forward, the 2024 KTM EXC range features a completely new LED headlight unit and light mask. The mask itself features improved triple clamp protection against roost and does away with the rubber mounting straps for improved fitment. Most importantly, the LED lighting unit provides 300% more illumination, making riding in the dark a completely new experience.
